kernel-module-emlog: Use compile task from module bbclass

This ensures that right CC/LD is used when building the module, which
should be KERNEL_CC and KERNEL_LD, otherwise it starts to use DISTRO
default ld and cc which could be non-gcc and non-bfd liker which is must
for building kernel and modules

Also hides a gold linker failure seen on aarch64
